Bug ID: 108973
Summary: Sufficiently narrow terminal window causes selftest
failure
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: acoplan at gcc dot gnu.org
Target Milestone: ---
Running the selftests in a sufficiently-narrow terminal window (in my case
$COLUMNS < 42) causes the following selftest failure:
$ echo $COLUMNS
41
$ ./xgcc -B . -c -xc /dev/null
-fself-test=$HOME/toolchain/src/gcc/gcc/testsuite/selftests
/home/alecop01/toolchain/src/gcc/gcc/diagnostic-show-locus.cc:4452:
test_add_location_if_nearby: FAIL: ASSERT_STREQ (" struct same_line { double x;
double y; ;\n" " ~ ^\n", pp_formatted_text
(dc.printer))
val1=" struct same_line { double x; double y; ;
~ ^
"
val2=" truct same_line { double x; double y; ;
~ ^
"
